As an important resource with wide distribution and abundant reserves, phosphate rock is concentrated in Sichuan, Guizhou, Yunnan, Hunan and Hubei. Due to the wide variety of phosphate rock crushing equipment on the market, when selecting equipment, it is necessary to comprehensively consider key factors such as material hardness, expected output, and inlet and outlet particle size to ensure that the equipment is adapted and operates efficiently. The following introduces how to configure the phosphate rock crushing and screening solution:

In the phosphate rock crushing operation, the selection of crushing equipment type and the determination of specifications are affected by many factors. Material properties, such as hardness, density, viscosity, clay content, moisture content and maximum feed particle size, as well as processing capacity, crushed product particle size, equipment configuration, etc., are all considered. Commonly used crushing equipment is rich and varied, including jaw, impact, hammer, cone and roller crushers, each with its own applicable scenarios.

1) Determination of coarse crushing crusher type

In the coarse crushing of ore, jaw crusher and heavy hammer crusher can be selected. When processing medium-hardness phosphate ore, impact crusher is also applicable. For example, the CJ European version jaw crusher has a processing capacity 2.5-3 times that of an ordinary jaw crusher, but it has a complex structure, a heavy body, high equipment, and is expensive. In view of the small processing capacity of the coarse crusher required this time, after comprehensive consideration, it is more appropriate to choose an ordinary jaw crusher.

2) Determination of the type of medium crushing crusher

For medium crushing equipment for phosphate ore with medium crushability, standard cone crushers, impact crushers, and hammer crushers can be selected.

The processing capacity of the medium crushing is 144t/h, the feed particle size is less than 200mm, and the discharge particle size is less than 30-80mm. The processing capacity of the roller crusher is too small, and the investment of the standard cone crusher is too high. The type of medium crushing crusher should be an impact crusher.

3) Determine the type of fine crushing machine

The fine crushing capacity is 160t/h, the feed particle size is less than 80mm, and the discharge particle size is less than 15mm. The fine crushing jaw crusher has low processing capacity, and the short-head cone crusher has high equipment investment. The impact crusher should be selected for fine crushing.
